2Wire modem giving me wrong IP address

Hi -

I don't know what I did to cause this, but one of the systems on my home network is no longer getting the 192.168.1.NNN IP address. Instead, I'm getting assigned my public IP address, which causes problems getting to this system from other machines on the network.

Any ideas? I've rebooted with no change in results. Thanks for any ideas.

EDIT: the system in question is a Mac, running 10.6. It's worked with 2Wire for ages.

1. All inbound traffic, except traffic which has been specifically assigned to another computer using the "Allow individual applications" feature, will automatically be directed to this computer. The DMZplus-enabled computer is less secure because all unassigned firewall ports are opened for that computer.

Note: Once DMZplus mode is selected and you click save, the system will issue a new IP address to the selected computer. The computer must be set to DHCP mode to receive the new IP address from the system, and you must reboot the computer. If you are changing DMZplus mode from one computer to another computer, you must reboot both computers. The new IP address you aquire is the RG's public IP address so it can be seen to the outside world.

2. Other systems simply have a 192.168.1.x IP (unless otherwise specified) and communicate with the RG as normal.

3. It will not affect your sharing speeds on the LAN, simply from the LAN to the WAN and vice-versa.
